-   Magnetism is not an energy in itself. Magnets have a force, and if that force is used to move an object over a certain distance, the energy is called work. If energy is … used to hold an object attracted or repelled by the magnet from moving, then there is potential energy stored in the held object/magnet system.

- Magnets are made by exposing ferromagnetic metals like iron and nickel to magnetic fields. When these metals are heated to a certain temperature, they become permanently magnetized. It's also possible to temporarily magnetize them by using a variety of methods you can try safely at home.

What is a Magnet? A magnet is an object or a device that gives off an external magnetic field. Basically, it applies a force over a distance on other magnets, electrical currents, beams of charge, circuits, or magnetic materials.Magnetism can even be caused by electrical currents. magnet is an object or a device that gives off an external magnetic field.

- In the 19th century, it became clear that magnetism was not a separate force, but was always produced by the action ofa. electric charges that were in motionb. the gravitational pull of the Earthc. the strong nuclear force acting on electronsd. light moving through a vacuume.

- ‘When you picked up the clip with the magnet the clip was accelerated toward the magnet acquiring kinetic energy.’ ‘A spinning superconductor acts like a very weak magnet, with the poles of the magnet precisely aligned with the axis of the spin.’ ‘Hutter spinels are strongly magnetic and can be separated from crushed samples of the rock with a hand magnet.’

Magnetic energy Magnetic energy and electric energy are related by Maxwell's equations. The potential energy of a magnet of magnetic moment m in a magnetic field B is defined as the mechanical work of magnetic force (actually of magnetic torque) on re-alignment of the vector of the magnetic dipole moment, and is equal:

- All magnets are made of a group of metals called the ferromagnetic metals. These are metals such as nickel and iron.Each of these metals have the special property of being able to be magnetized uniformly. When we ask how a magnet works we are simply asking how the object we call a magnet exerts it’s magnetic field.ll magnets are made of a group of metals called the ferromagnetic metals. These are metals such as nickel and iron.

How Magnets Work A whole magnet's magnetic moments come from the moments of all of its atoms. An iron atom and its four unpaired electrons. In metals like iron, the orbital magnetic moment encourages nearby atoms to align along the same north-south field lines. Iron and other ferromagnetic materials are crystalline.

Electric and Magnetic Fields Magnets function as transducers, transforming energy from one form to another, without any permanent loss of their own energy. General categories of permanent magnet functions are: Mechanical to mechanical-such as attraction and repulsion. Mechanical to electrical-such as generators and microphones.

Q & A: How do magnets work? A: Dear Anonymous, As you point out, you can't create energy with magnets, but you can store energy. When you push two same-sign poles together it requires energy. This energy can then be released and do useful work when you let go of the magnets.: 1) You could always remove the energy for use once, just by letting two oppositely polarized magnets attract and do work as they approach each other. That's just like how you can get work out of letting some object fall in a gravitational field or from the attraction of opposite electric charges.

Figure you need about 175 grams for the first week and about 70 grams a week thereafter. At this consumption rate, 500 grams will last about 1 1/2 months and 1000 grams will last about 3 months. The Creatine Dose Table below shows how much you might need depending on your weight and how hard you train.tudies have shown just taking the maintenance dose of about 5 grams a day will accomplish the same result as loading except that it will take 3-4 weeks for your system to reach saturation levels as opposed to only 1 week when you load. So the benefit to loading is quicker results, not greater results.

Questions and Answers Magnets are used extensively in high energy and nuclear physics. We use some of the most powerful magnets in the world and certainly some of the coldest. Ok, to answer your question. Yes, I know what an electromagnet is. I have to assume you want to know a little more than that. An electromagnet is a magnet that is created when electricity flows through a conductor. The magnetic field goes around the conductor. The typical way electromagnets are built is to wrap many coils of wire around a ferromagnetic core (almost always iron).

How Magnets Work Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field's lines of force exit the magnet from its north pole and enter its south pole. Permanent or hard magnets create their own magnetic field all the time.

Excitation (magnetic) The rotor iron retains a magnetism when the generator is turned off. The generator is started with no load connected; the initial weak field creates a weak voltage in the stator coils, which in turn increases the field current, until the machine builds up to full voltage.

Properties of Light Electric and magnetic fields oscillate together but perpendicular to each other and the electromagnetic wave moves in a direction perpendicular to both of the fields. Light, electricity, and magnetism are manifestations of the same thing called electromagnetic radiation. The energy you see coming out of the computer screen you are using to read this page is made of fluctuating electric and magnetic energy fields.

How Magnets Work Iron filings (right) align along the magnetic field lines of a cylindrical neodymium magnet. To understand the answers to these questions, it helps to have a basic definition of a magnet. Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field's lines of force exit the magnet from its north pole and enter its south pole. Permanent or hard magnets create their own magnetic field all the time.

- We can store cold (ice), heat (i.e. hot water bag) and electrical charge (batteries). We can even store a magnetic field in a magnet. We can convert light into energy and then, if we want, back to light. But we can't store light in form of light in significant amounts.

- Answer by Methuselahmagee. Confidence votes 195. In order for Kinetic energy to be converted into electrical energy, the kinetic energy usually drives the rotation or oscillation of a magnet in close proximity to coiled wire. A bar magnet can be moved up and down through the centre of a looped coil of wires.t works by inducing an electric current in a loop of wire by using magnetic fields.   An electrical generator or Dynamo. The mechanical energy moves a magnetic field relative to electric coils and creates electricity. Little Dynamos on bicycles provide light at night.

Energy is the capacity to do work El Hombre Invisible. Energy is isn't just the capacity to do work. It is also the capacity to transfer heat. It can also be mass. Kinetic energy is the energy you have by lieu of your movement. When you do work to move something, that energy is not lost but is conserved, in this case in the form of kinetic energy.

- There is no energy involved in maintaining a magnetic field from a permanent magnet. The reason is because the magnetic field comes from the intrinsic spin of the electrons in the atoms of the metal. It requires no expenditure of energy to function.

MAGNETISM Magnetism, along with electricity, belongs to a larger phenomenon, electromagnetism, or the force generated by the passage of an electric current through matter. When two electric charges are at rest, it appears to the observer that the force between them is merely electric.
